The Siskiyou Mountains are unusual because they run east and west to form a bridge connecting the Coast Range and the Cascade Mountains. This connection allows plant species from these different regions to meet and intermix. Mt Isabelle is mostly covered with a mixed conifer forest on its lower flanks and near the summit, the forest thins and it is mostly brush and grass covered.

Getting There

To find the trailhead from Interstate 5 in Medford take either the North or South exit from I-5 and follow the signs to Jacksonville and Hwy 238. Jacksonville is a quaint historical town located about 6 miles west of Medford. The whole town of Jacksonville is on the National Historic Register because of its well preserved buildings from the 1850’s when gold was discovered nearby. After driving through the middle of Jacksonville continue on Hwy 238 towards Grants Pass. About 4.7 miles from the stop sign on Hwy 238 and Oregon Street, turn right on the paved Forest Creek Road.

Forest Creek Road is paved for the first mile and then turns to a great dirt road. There are many homes along here on both sides of the road, so watch for pedestrians, animals, and OHV’s. At 2.5 miles from Hwy 238 stay left and at 4.2 miles turn left on Oregon Belle Road. Oregon Belle Road is paved, but it is narrow and crooked. Stay on Oregon Belle for 2.4 miles up to a ridgeline saddle. Turn right on the gravel road and stop at the gate about 100yds up the road. This is the trailhead and the elevation here is 3,510ft.
